The standard height of ceilings is usually 2.4 metres. But some people choose up to three metres. This can give the house a feeling of space, grandness and elegance, but it will probably add to your building costs.
However, according to real estate agents, homes with higher ceilings generally fetch better prices than similar quality homes with the standard ceiling heights.
Consider mixing the ceiling heights, for example having lower ceilings in your bedrooms and adding height in the living spaces.
Higher ceilings will require heating with circulation systems to spread the heat and air evenly.
